In Response To 'Re: Re: Play[a sum of Harmonics]'---------As yehuda says just having harmonics isn't enough.
Try setting up some sliders for the amplitudes of a few harmonics.
I would change SampleDepth->16, SampleRate->20000

I'm wondering whether it is important that the ear choosesthe lowest as the fundamental - maybe you need to make this louder than the rest??

Don't forget the ear is most sensitive about 1K so make this the lowest perhaps or boost up the lower frequencies quite bit -let us know how you get on ...interesting ...
